The problem is that the fan is not very good, and it go very very fast. An other problem is the extreamer pcb switched speed control, it´s made a small sound like a buzzing on the fan. So I had cut the cable of the fan and I put one resistor about 56ohms in serie with the fan to reduce de speed and put in paralell with the fan a capaciter about 100nf to reduce de switching noise.
